Kendall Jenner has changed a lot since she first appeared on “Keeping Up With the Kardashians.” In eight years, Kendall has gone from a preteen to a supermodel — and she just got a huge 20th birthday gift. On Tuesday (Nov. 3), Kendall broke the news that she and best friend Gigi Hadid will be walking in the Victoria’s Secret Fashion Show on Dec. 8.

Jenner called the gig a “dream job” and says it’s “always been one of [her] biggest dreams to be on this catwalk.”

In other news for the birthday gal, she posted a letter that she wrote when she was only fourteen on her website.

“I am modeling right now and I LOVE it! I am also on a show called ‘Keeping Up With the Kardashians’ and we are filming Season 5,” Jenner writes. “My goal in life is to become a big time model and travel to really amazing places. I really hope it happens! =)”

In another post on her site, Jenner counted down twenty new goals that she has for the upcoming year. Each of her sisters got a shout out in the list. “Organize my candy jars as well as Khloe. Perfect my contour game like Kim. Master healthy food like Kourtney. Be as self-confident as Kylie,” she writes.

And the Kardashian-Jenners all posted something sweet on social media to celebrate Kendall’s birthday.
